Explain how soaring and gliding birds use their air currents in their flight

1 answer:

8 0

Soaring and gliding birds like eagle, vulture, albatross, sea gulls etc are efficiently adapted to utilize the air currents in their flight.

Explanation:

The soaring flight and gliding movements are special adaptation developed by birds to meet the challenge of increasing turbulent air current.

Birds have the extraordinary skill of flying smoothly and effortlessly even at very high altitudes

Birds soar by using thermal and dynamic soaring techniques.

Gliding movements help the birds to deflect the wind downward which helps to lift their bodies in the air. They do not flap their wings during gliding but just dive straight into the air which helps to increase their speed.

The adaptation of the bird’s structure with very light but strong bones on their wings helps to soar and glide in the air.

The ATP made during glycolysis is generated by :

ASHA 777 [7]

Answer:

The correct answer is A. Substrate-level phosphorylation

Explanation:

During the substrate-level phosphorylation, phosphoryl group is directly added to ADP or GDP to form ATP or GTP from phosphorylated intermediate rather than from inorganic phosphate like in case of oxidative phosphorylation.

So in glycolysis 4 ATP are produced by substrate-level phosphorylation. Apart from the 4 ATP, 2NADH are also produced during the glycolysis which is used during the oxidative phosphorylation and produce 4-6 ATP.

So ATP made during glycolysis is generated by substrate-level phosphorylation as ATP is produced by direct addition of phosphoryl group from intermediates.

Are Fungi beneficial or harmful? Explain

Nata [24]

Answer:

Honestly it depends...

Explanation:

I would say overall fungi are beneficial because they feed on dead organic matter. They recycle most of the carbon and release nutrients to be used by other organisms. They are also used for medicinal purposes. Not to mention yeast is a fungus and bread is yummy.

But certain fungi are deadly if ingested or linked to plant and human diseases. Also mold is a fungus and nobody likes mold.

What happens at the end of the transcription process?

Goshia [24]

Answer:

C) DNA produces messenger RNA, also called mRNA.

Explanation:

During transcription DNA is used as a template to make RNA. RNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. Translation reads the genetic code in mRNA and makes a protein.

A client has been diagnosed with otosclerosis. the nurse explains to the client that this is a common cause of hearing impairmen

expeople1 [14]

The right answer is spongy bone (cancellous bone).

In otosclerosis, the new bone blocks the movement of the stirrup, causing transmission hypoacusia. Otosclerosis can also cause perceptive deafness, especially when otosclerotic bone foci are close to scala media. Half of all cases are hereditary. The measles virus may play a role in triggering a genetic predisposition to otosclerosis.
